The Four Seasons of Horsetooth Mountain Bike Challenge is a grass-roots un-event with no entry fees and no real start times and is ridden on the two solstices and two equinoxes in Horsetooth Mountain Park and Lory State Park.
By being required to complete at least three seasonal stages, we hope it encourages you to come ride if your schedule doesn’t permit on any given stage. The course is designed to offer what we think are the best sections of trail in our backyard. The course should take about 2-3 hours.
Trailforks scans users ridelogs to determine the most popular direction each trail is ridden. A good flowing trail network will have most trails flowing in a single direction according to their intension.
The colour categories are based on what percentage of riders are riding a trail in its intended direction.
